the; embodiment of; the invention as here shown the sizing machine orslasher section 15011 slashing the warp yarns i-s organized as follows:Suitable end-frames orstandards 2 support a size-vat 3 constructedin theform of a tank or trough. The size vat 3 hasend members 4 provided withbearings for the end journals of two shafts 5 and '6 which carry thecoppersize-rolls 7 and Sextending horizontally across the size-vat toadapt theml to partially immersed in the starch or sizing-fluid Scontained therein. At one endv 01; the shafts 5" and 6' are meshing witha driving-gear ll journaled on the end-member 4. The drivinggear 11carries a bevel-gear12=on its side from which it is driven through'themeans of: a bevel.- pinion 15 fast on a shaft 1-6. The shaft 16 isjournaled in a bearingll'fl attachedtothe side of" the end-frame orstandardQ, and

gears 9 and 10 I extends to the right of the machine to adapt 7 it to,be connected with any Of power. Usually the shat-t 16 is connected to,the winding-drum on the drying end of the slasher, not hereinshown, tobe driven fromv the power mechanism thereof:

suitable source At the. receiving end of the machine are 7 suitableguiderollers l9and across which the warpfyarns' to lead. as theyfeed-into the size-vat 3 from the section-beams, not herein shQwn. Therollers 19 and 20 have'trun-n nions 21 and 22 journaled in suitablebearings at the top ofthe end-members 4 of the vat. Within the vat 3 isanimmersion-roll 23 having its end-gudgeons 24 supported from pendant inFig. 1. The arms 25 are connected at their upper ends tolvertical-racks26 arranged at eitherend ofthe vat on the outside not the. end-memberstp The racks 26 are adapted toeslideup and down to raise and lower theimmersion-roll 23 in the vat m regulateits degreeofi submergence in theingwfiuid S in accordance with the level thereof. The racks-26 areoperated from DQ119115 2-? at the ends of" shafts 28' which arejournaled in bearings 29 on the standards z." The Shafts 2S carry wo-rnrgears meshing with worms 31 on a horizontal cross shaft On theend'of the shaft 32' is hand-wheel 33 by means of which it may bemanually rotated to. turn the shafts 2810 raise and lovYenthe. racks.26' in accordance with the usuaharrangement arms 25 shown by dottedlines from the section-beams, not herein shown, across the guide-rolls19 and 20, thence down under the immersion-roll 23 and up over thesize-rolls 7 and 8, whence they lead to the drying section of themachine. Above the size-rolls 7 and 8 are the squeeze-rolls and 36arranged with their peripheries hearing against the size-rolls. Thesqueeze-rolls and 36 have journals 3'? and 38 constituted by reducedportions of their axial shaft-s 39 and 40, see also Fig. 2. The journals37 and 38 are received in slotted bearings 41 and 42 formed as a part ofand projecting upwardly from the end-members 4 of the size-vat 3.

In my new and improved construction of the squeeze-rolls I provide thebarrels of the rolls with end-flanges or heads 43 and 44 which overlapthe ends of the lower sizerolls or drums 7 and 8. These flanges may beof relatively thin metal, preferably brass, and are employed to sustainand hold in place the roll-covering which is applied to the peripheralsurface of the squeeze-rolls. I also provide the squeezerolls and 36with spurgears 45 and 46 mounted fast on their shafts 39 and at the sideof their end-flanges. The gears and 46 serve as means for connecting thesqueezea'olls to drive the mechanism which applies the outersurface-covering to the barrels of the rolls.

As shown more particularly in Figs. 2 and 3, the present improvedmechanism for applying the covering to the squeeze-rolls comprises meansfor winding onto the barrel of the rolls one or more layers of strandsof textile material such as cotton or worsted yarns. Preferably, Iemploy cotton yarn for the covering of the first roll yarn for thefinishing-roll 36, but it is to be understood that the character of thecovering material may be varied in accordance with conditions and theresults desired. In accordance with the preferred practice, the barrelsof the squeeze-rolls are first covered with a layer of relativelyflexible or resilient material, such as soft felt, before the textilestrands are applied thereto. As shown in Fig. 2, a strip of felt f isfirst wound spirally of the barrel of the squeeze-roll 35 with its edgesabutting to provide a smooth, unbroken surface. The strip of felt hasits ends cut to match the spiral winding so that they do not overlapwhere they terminate at the end-flanges or heads 43 of the roll. Themethod of cutting, laying and matching the felt strip on the barrel ofthe roll is more fully described in my companion application for U. S.Letters Patent, Serial No. 18,547, filed concurrently herewith; thepresent application relating more particularly to the means andmechanism for applying the surface covering to the roll. To apply thissurface covering of strands over the layer of felt on the barrel of theroll 1 and worstedmake use of a strand-laying mechanism which isorganized with the operating mechanism of the machine as next explained.

The strand-laying mechanism is designed to adapt it to be built intomachines of standard type to serve as a permanent partthereof. Tosupport the strand-laying mechanism from the machine I may employ anysuitable form of brackets or standards mounted on the main framethereof. As shown in Figs. 1 and 2, I attach to the endmembers 4 of thesize-vat 3 a pair of brackets or arms 50 of inverted L-shape which arefastened in place by means of bolts 5i. At the forward ends of the arms50 are clongated hubs or bearings 52, in which is journaled a rotatablescrew-shaft The screw-shaft 53 is held in its bearings 52 by end-collars54 secured in place by suitable means such as the set-screws Preferably,the end-collars are formed with rounded flanges 56 providing hand-wheelsby means of which the shaft 53 may be rotated manually for a purpose aslater explained. The shaft 53 is formed with helical thread-grooves 57and 58 of rightand left-hand pitch or, in other words, the shaft iscross-threaded along substantially its en tire length.

Slidable longitudinally of the shaft is a sleeve 60 having a.rearwardly-extending arm 61, see Fig. 4, constituting acarriage forcarrying the supply of yarn Y, the strands of which are to be laid onthe surface of the barrel of the squeeze-rolls and 36. The arm 61terminates at its rearward end in a fork 62 arranged to straddle across-rod 63 which extends between the brackets or arms 50, beingsecured thereto by means of suitable nuts 64. The crossrod 63 serves asa brace or tie for the arms 50 and preferably carries a tube or sleeve65 which forms a bearing for the fork 62 of the arm 61, see Fig. 4. Thesleeve 65 is usually made of brass to prevent rust or corrosion.Projecting upwardly from the arm 61 is a rod or standard 66 having itslower end bent into an eye 67 which is tened to the arm by means of abolt 68. The

rod 66 is bent at substantially right-angles at its upper end to providea spindle 69 for rotatably supporting the yarn-cop or package Y. The copor package Y is preferably of cylindrical shape, wound with multiplestrands of yarn laid in a cross-wind to render the package selfsupporting without the use of spool flanges. If preferred, however, aspool may be used in place of the cylindrical cop or package Y. Usuallythe package Y is wound on a cylindrical wooden tube T having an axialbore for receiving the spindle 69 on which the cop turns. The spindle 69may be set at a slight angle to the horizontal so thatthe package willmaintain its position thereon by gravity with the from its opposite endof the tube T bearing against the upright portion of the rod 66. Aperipheral groove t is cut in the periphery of the projecting end of thetube T ceive a cord or thong 70'of leather or the like looped overthetube and bearing a weight 71 at its end to cause it to act as a fi,.:tion-brake to control the rotation of the package. As shown in Figs. 2and a, one end of the cord 70 is fastened in a hole 72 in the rod 66 andthe cord leads up over the tube T with the disleweight 71 suspended endzFastened to a boss 73 on the underside of the arm 61 is a wirestrand-guide 74- held in place by a screw The guide 74% has two branches76 and 77 formed at their ends with loops or pigtails through which thestrands 3 lead as they draw down to the squeeze-roll. The upper branch76 of the guide directs the strands 3 from the periphery of the packageY across the top of the screw-shaft 53 and thence they lead down throughthe pigtail on the other branch 77 to feed them on to the barrel of thesqueeze-roll.

The sliding sleeve 60 is formed with a slot 78 at its center adapted toreceive a crescent shaped follower 79, see Figs. 2 and 1, which engageswith the thread-grooves 57 and 58 of the screw shaft 53. The follower 79is carried by a plunger-pin 80 which is slidable in a bearing 81fastened to a boss 82 on the top of the arm 61 by means of a screw 83. Ahelical spring 85 surrounding the plunger 80 between its bearing 81 andthe follower 7 9 acts to press the latter downward to maintain it inengagement with the threads of the screwshaft 53. The top of the plunger80 is preferably knurled to provide a finger-hold so that the plungermay be pulled upwardly to disengage the follower 79 from thethread-grooves when it is desired to manually adjust the sleeve alongthe screw-shaft 53. It will be obvious from the above description thatwhen the shaft 53 is rotated the sleeve 60 will be traversedfirst in onedirection and then in the other through the engagement of its follower79 with the thread-grooves 57 and 58; it bciig understood that when thefollower reaches the end of one of the thread-gr0oves it is guided bythe curved portion thereof to turn or swivel in its bearing to direct;it into the reverse thread tocause the traverse of the sleeve in the"opposite direction, this being a usual arrangement for traverse-lmechanisms. p

The screw-shaft driven from the squeezeu olls by means of the geared-5and 16 at their ends which are fast on the rollshafts 39 and 40, aspreviously explained. It is to be understoodthat the strand-applyingmechanism is both of the squeeze-rolls and 36 and to adapt it to adaptedfor use with therefore the driving mechanism for the screw-shaft 53 isadjustable in position so that it may be connected to be driven fromeither of their respective gears 4-5 and 46. For this purpose thedriving mechanism for the screw-shaft 53 is carried on an adjustable armwhich is pivoted to swing about the axis of the screw-shaft, see Figs. 2and 3.

Referring to :Fig. 2, the mounting for the arm 88 comprises a separatehub 89 which is rotatable on the shaft 53; The hub 89 is heldlongitudinallyof the shaft 53 abutting the side of a gear 90 which hasits hub 91 secured to the shaft by suitable means such as a set-screw92. The gear 90 is made in the form of a sprocket to adapt it to bedriven by a chain 93 passing over a second sprocket 9%. The sprocket 94is fast on the hub of a gear 95 which is journaled on a stud 96 carriedat the end of the arm 88. The gear 95 is adapted to mesh with the gearat the end of the roll 35 in one instz .e and in the other with the gear46 on the roll 36,.see particularly F 3. The stud 96 forming the journalfor the gear 95 extends through the arm 88 and screws into a handle 97which serves as a convenient means for manually shifting the arm 88. Thehandle 97 is scored with a groove 98 to adapt it to receive a wirehool:99 which is sprung over the shaft 39 or the shaft 10, as the case maybe, to hold the gear 95 in mesh with the respective driving gear on oneor the other of the squeeze-rolls 35, 36.

.Referring now to Fig. 2, the hub 89 is held against the side of thegear 90 by a collar 103 secured to the shaft 53 by suitable means such*as theset-serew 104. A portion of the hub 89 is turned down orreducedin diameter at 105 to provide'a bearing fora slotted portion 106 of thearm 88 see Fig. 3. As shown int-his view the arm 88 is widenedthroughout substantially half of its length and provided with thelongitudinal slot 107 which fits the reduced portion of the hub 89. Onthe hub 89 is'a boss 108 from which extends a rod 109 held therein bymeans of a set-. crew 110 shown in Fig. 3. The arm 88 is provided on itsside with a. lug or hearing 111 which is bored to receive the rod 109 toadapt it to slide therein. One side of the rod 109 is slotted at 112 anda thumb-screw 113 screwed through the side of the lug 111 is adapted tobind against the slotted portion to hold the rod from sliding in thelug. lVhen the thumb-screw 11-3 released the arm 88 may he slid as awhole on its hub 89, whereby to lengthen or shorten the distance betweenthe gear 95 and shaft 53 in accordance with require ments to engage thegear with one or the other of the gears 45,46. After the gear 95 hasbeen brought into mesh with the drivinggear on theppropriatesqueeze-roll Cl l the arm is held in its adjusted position by tighteningthe thumb-screw 113 against the rod 109 to prevent further slidingmovement.

In order to compensate for the change in.

relation between the sprockets 90 and 9% during the adjustment of thearm 88 and the consequent tightening or slackening of the chain 93, Iprovide an idler-sprocket 11a at the upper end of the arm. Theidlersprocket 114: is journaled on a stud 115 at one end of a lever 116which is pivoted at 117 to the upper end of the arm 88. A spring 120 isanchored to the arm 88 at 121 with its opposite end connected to the endof the lever 116. The spring 120 acts to rock the lever 116 to maintainthe sprocket 11% under tension whereby to take up the slack in the chain93.

The method of operation of my improved rollcovering means as employed ona slasher section having a. plurality of squeeze-rolls is as nextexplained. For covering the first roll 35 the strand-laying mechanism isarranged as illustrated in Figs. 1 and 2, and shown by dotted lines inFig. 3. That is to say, the arm 88 is drawn out or lengthened byreleasing the thumbscrew 113 and sliding the arm on its hub 89. Afterthe arm has been lengthened sufficiently to bring the gear 95 in meshwith the gear 15 on the roll 35 the tlnnnb-screw 113 is tightenedagainst the rod 109 to hold the arm rigid with its pivot. The hook 99 onthe handle 97 is then hooked around the roll-shaft 39, as shown in Figs.1 and 2. to hold the gear 95 in mesh with the gear L at the end of theroll 35. The tape of strands'y from the multiplewound package of yarn Yis then led through the pigtail-guides on the branches 76 and 77, asshown in Fig. a, and thence drawn down to the barrel of the roll 35 andthe ends secured thereto.

ll. has been stated that the barrel. of the roll 35 is usually coveredwith a strip of felt f wound spirally thereof with its ends matched toprovide a smooth surface without overlapping seams, but in some casesthis felt covering may be omitted. In starting to wind the outer covermgof strands on the squeezeroll the traverse-carriage or sleeve 60 isfirst adjusted in position at one end of the screw-shaft 53. Usually thewinding is started at the right-hand side of the machine, viewed as inFig. 2, and by lifting the rod or pin 80 to release the follower 79 thesleeve may be slid along the shaft to engage the follower with the endof the screw-threads. This adjustment of the sleeve 60 will bring thestrand guide 74 into position with its pigtail yarnguides directly overthe end of the barrel of the roll 35, the ends of the strands 2 beingattached to the barrel at this point. Usually the ends of the strip offelt f are attached. to the metal barrel of the roll 35 by means oftacks driven into wooden blocks set into holes at the ends of the barreland the ends of the strands i/ may be secured in the same manner.

WVhen power is applied to the machine through the drive-shaft 16 thepinion will drive the gears 11 and 12 in the direction indicated by thearrow at in Fig. 1. The gear 11 will therefore transmit rotation to thegears 9 and 10 on the size-rolls 7 and 8 to turn the latter in thedirection indicated by arrows b. It has been explained that thesqueeze-rolls and 36 are mounted to slide in their bearings 41 and 42 sothat their peripheries bear on the surface of the size-rolls 7 and 8under the weight of the squeezerolls. Through this frictional contactbetween the surfaces of the cooperating size-rolls and squeeze-rolls thesqueezerolls will be driven in the direction indicated by the arrows 0in Fig. 1. As the roll 36 is turned in this direction the tape of yarns1 leading thereto will be wound on to its barrel in the mannerillustrated in Fig. 2. and meanwhile, the gear 45 on the squeeze-roll 35will drive the gear 95 on the arm 88. The gear 95 transmits motionthrough its sprocket 94 and the chain 93 to drive the sprocket 90 whichis fast on the screwshaft is thus rotated at a relatively slow rate ofspeed and the engagen'ient of the follower 79 with its threads causesthe sleeve to be traversed therealong. That is to say, when thescrew-shaft 53 is rotated in the direction indicated by the arrow d inFig. l the follower 79 engaging the left-hand thread-groove 58 on theshaft causes the sleeve 60 to be propelled to the left as viewed in Fig.2. The sleeve 60 and the yarn-supply carrier will thus be caused totraverse slowly along the screw-shaft 53 to cause the tape of strands yto be fed toward the left-hand end of the squeeze-roll The traverse 0fthe sleeve 60 is timed to lay the tape or band of strands l in a spiralor helix-with the strands closely adjacent and substantially coveringthe barrel of the roll. The length of the threaded portion of thescrew-shaft 53 is so proportioned that when the follower 7 9 reaches theend of the threads the strand-guide will be just above the end of theroll 35 so that the tape of strands will be laid close up to theend-head or flange 4.3 of the roll. At this point the follower 79 feedsthrough the curved end-portion of the thread-groove and is directed intothe right-hand groove 57. Therefore, as the shaft 53 continues to turnthe sleeve 60 will be carried back in the opposite direction and thestrand-guide 74 is thus caused to feed the strands toward the right-handend of the roll. The strands of yarn or other material may thus be laidon to the barrel of the roll in another layer The screw-shaft 52 i Ill)' gear 46 with .under power and the strands guided by the traverse-meansas beforeeX-' and the operation may be continued to aply as many layerstothe roll as required; l Vhen the last layer is completed the end ofthe tape of strandsis cut from the supply and fastened tethe roll in anysuitable manner.

After the surface covering has been applied to the first squeeze-roll35, the finishing-roll 36 is covered in the same manner by adjusting thestrand-applying mechanism to the position shown in full lines in Fig. 3.For this purpose the arm 88 is shortened'by releasing the tlnimb-screw113 and sliding the arm on its hub 89. After "the gear 95 has been setin position engaging the gear 416 on the shaft 40 of the roll 36 thethumbscrew 113 is tightened against the rod 109 and the hook 99connected withthe shaft 4-0 to hold the gears in mesh. The tape of yarnstrands g is then led down tothe barrel of the roll 36, secured theretoadjacent one of the end-heads, and the traverse of the sleeve 60 startedatthe appropriate end of .the screw-shaft The turning-of the the roll36drives-the gear 95, sprocket Stand chain 93 to drive thegear 90 torotate the shaft 53,and the sleeve 60 is thus traversed in the manner asbefore described to feed the strands onto the barrel of the roll in asmany'layers as required.

It has been explained that the copper drum or barrel-of the squeeze-rollis 'preforably first covered with a spirally wound strip of felt or likeresilient material before the outer covering of yarn is'iaid thereover.In some cases, however, where a'harder, less flexible covering isdesired the yarn'mayb'e wound directly onto the metal barrel of the rollwithout the yieldable base. In either res e the method of adjusting themachine and operating it to traverse the strands to lay them on the rollis the same. It is-tobe understood that the felt base is appl'ied'to theroll before the machine placedin operation for slashing. -Usnailythemachine is driven in low gear and the strip of felt guided on to theroll byhand, and after hasbeen tacked in place the yarn'strands arewound thereover with the machine operating automatically plained.The'initial covering of strands is usually applied to the roll beforetheslashina operation is started,'but it is to be particularly noted "thatthe outer covering of strandsmaybe renewed at any time during the normaloperation of'the machine while thoslashi'ng operation is taking place.In fact, it is the preferred method to apply the strand covering whilethe machine is op warp "passing there-' erating to slash the through.

It has beenexplained that the warp yarns w in the'formofa sheet are fedinto the machine over squeeze-roll, which the guide-rolls '19 and 20,

thence passed down under the innnersionroll and led up over the firstsize-roll 7 and then across the .top of the second sizeroll 8. As thewarp is thus drawn through the machine it is immersed in the starch orsizing-flnid S in the tank or vat 3 and as it passes over therotating-drums ,or rolls 7 and 8 the squeeze-rolfs 35 and 36 bear downagainst the drums to workthe fluid into the yarn while squeezing out allsurplus fluid before the warp passesout ofthe machine. Ithas beendemonstrated that with my improved rolls covered with strands as hereindescribed the action of the rolls on (the warp yarns has a verybeneficialetl'cct. This is due to the fact that the coils of yarn on thesqueeze-roll coincide substantially with the parallel arrangement of theyarns in the warp whereby the surface of the roll conforms more'closelyto the surface of the warp. The roll is preferably covered with a numberof strands approximately eqnal to the number of yarns in .the warp and 1hence the windingson the surface of the squeeze-roll have, a tendency toseparate the yarns in the warp and to knead and work the size into theyarns on the sides thereof to effect a more thorough, sizing of thewarp. Furtl1er11'i0re,"tlie surface .of the may be described as more orless corrugated due toflits make-up of alarge number of strands, has acombined squeezing and combing action on the warp yarns tending to combout and straighten the fibers and tolay them more smoothly in place, andalso a cleaning action to brush ofl any dirt or foreign matter..Moreover, as the surface of the 1011 conforms more nearly 'to thesurface of the 'warpthere will be less tendency to flatten the warpyarns and hence the yarns emerge from the sizingprocess in a smoother,rounder state without being fiattened or disturbed in twist.

. By applying the outer covering to the roll with continuous strandswound on to its barrel the surface of the roll is made exactlyCOllCQDtl'lC with its axis so that there are no. hi'g'h andlow points.This results in a more even pressure ofthe squeezea'oll on the Warpduring the continuous rotation thereof, the roll having no tendency torise-and fallas is the case where its periphery eccentricwithrespecttoits axis. i r

As another advantage of the present im-' proved roll-covering there areno s ams, bnnches'or protnberances on the surface. of, the roll as isthe case with a roll covered with blankets. 'Heretofore the commonpractice has been to recover the roll with a blanket of wovenmaterial-wrapped therearound. )It is obvious that a roll covered with afabric blanketwill not'have a surface concentric withjits axis andhence: the roll will rotateout of true with a rising and falling'motionasit bea-rs on the warp. This luU causes an uneven squeezing pressure sothat the warp is not uniformly treated throughout its entire length.Furthermore, a blanket-wrapped roll has a lapped seam extending acrossits length formed by the edge of the blanket and consequently each timethe roll makes a complete rotation this seam or ridge will leave a markacross the warp. The cross-threads of the fabric blanket are also apt toindent the warp, but with my improved covering there are no ridges,seams, or protuberances liable to mark the yarns being treated.

As a further improvement my present rollcovering is much more economicalboth in first cost and as regards its durability or wearing qualities.Moreover, it can be applied to the roll without particular skill orexpel-mess on the part of the operator and hence eliminates the chanceof poor workmanship. Its use also eliminates the hand labor and timerequired for manually covering a roll with blankets and effectssubstantial economies in this respect.

As a still further economy the present improved roll-covering will wearlonger than a blanket covering and may be renewed when required withoutstripping off the worn covering. That is to say, the strand-covering onthe roll may be applied while the slashing operation is being carried onso that there is no loss of production due to idle machinery. Both thefront-roll and the back-roll may be covered during the operation of themachine, as the invention provides for adjustment of the strand applyingdevice or traverse-mechanism from .one roll to the other as required. Itis therefore only necessary to remove the rolls from the machine afterlong periods of use when the outer covering has been renewed to such anextent that it has entirely filled the space between the end-flanges orspool-heads. This condition occurs only after the inner felt-coveringhas become worn or hardened to such an extent that it needs renewing,generally at intervals of from six months to a year, dependent upon thetime it takes for acid fumes from various compounds used in the size toeat into the surface of the roll. When this occurs the roll is taken outof the machine and its barrel trued up in a lathe and coated with whitelead. This does not necessarily mean that the machine remains idle,however, because a substitute set of rolls may be kept in reserve andapplied to the machine while the defective ones are being made ready forrecovering.

The improved strand-applying or covering-means is adapted for universalapplication to practically all types of slashers and starchers and maybe applied to use thereon without change in the basic structure of themachine itself.

The improvement is also adapted for other types of processing machines,such as starchmangles for starchmg or s /img fabrics. Such a type ofmachine is illustrated in Figs. 5 and 6 of the present drawings. Inthese views 125 designates the side frames of the machine which supportthe starch-vat or trough 126. A starch-roll or drum 127 is journaled inbearings at the sides of the starch-vat 126 with its periphery submergedin the fluid therein. Above the roll 12 7 is a squeeze-roll 128journaled in bearingblocks 129 which slide in vertical ways 123.ressure-screws 130 carrying hand-wheels 1251 are mounted in swiveledbearings one pair of levers 132 which are pivoted in bearings 183mounted at the top of standards 13% rising from the main frame of themachine. Connected to the outer ends of the levers 132 are pendant rods135 connected by turn-buckles 136 to rods 13? which are swiveled tolower weight-levers The ,levers 138 carry weight 139 tending to draw theupper levers 192 downward to apply pressure to the screws 130, which, inturn, act through the bearings 129 of the squeeze-roll 128 to cause itto press against the cloth or fabric C passing through the rolls. Thecloth 0 delivers from a roll 1 10, passes over and under a series oftensionbars 141, and thence draws betwe en the squeeze-roll 128 andstarch roll 12" to a wind-up roll 142. In this type of mach ne thestarch-roll 127 is driven from gearing 1 13 and through its contact withthe squeezeroll 128 it rotates the latter as the cloth passestherethrough. The squeeze-roll 128 is provided with flanges 1 1 1 and atthe outer end of its shaft 145 is a gear 1416. My 1mprovedfeed-mechanism for applying the strands to the surface or thesqueeze-r01 128 is supported from suitable brackets 1 1T attached to thesides of the standards 134. The mechanism of the device is identicalwith that previously described and comprises the arm 88 carrying thegear 95 at its end adapted to mesh with the gear 146 on the end of thesqueeze-roll shaft 145. The gear 95 carries the sprocket 9-1 whichdrives the gear on the traverseshaft 53 through the medium of the chain9?).

In thistype of cloth-processing machine there is usually only one set ofrolls acting on the fabric so that the covering-mechanism does notrequire to be shifted to cover the different rolls. However, themechanism is preferably of the same construction previosuly described toadapt it to be shifted out of the way when it is not required forcovering the squeeze-roll. It is to be understood that in the embodimentof the invention as last described the arm 88 may be rocked to shift itsgear away from the gears on the squeeze-roll 128, the arm beingsuspended by any suitable means while the coveringanechanism remainsinoperative.

S110 a i r r h-m neleedy n an i ing machines, a rubber-covered roll isem.- ployed to obtain the required. resiliency on its'surface, Thistype. of roll requires freq nt grin ing or-tlirning surface and asthethicknessof the covering is reduced there is a consequent loss of re?siliency, "With my improved strand-covering the roll does not lose itsresiliency during long periods of, use. and its surface maybe renewedwhen required at much lessYcost than with a rubber covering. Moreover,the rubber covering is liable to. vary in resiliency at differentpoints, that 1s, to have relatively hard and soft spots due to in,-equalities in the mixing or vulcanizing of the rubber, so that theyarn-covering is much superior being, substantially uniform inresiliency also less I tion from exposure to acid. fumes or climaticconditions,
